Obote Intelligent Dry Sorting Machine: Advanced Sorting Technology to Improve Efficiency and Quality in the Mining Industry
Release time: 2025-07-08
In the noisy workshops of traditional coal washing plants, raw coal mixed with gangue rushes down, and the large equipment used in water-washing coal continues to consume massive amounts of water and electricity. The muddy water is a major challenge for environmental management. However, Obote’s intelligent dry sorting machine, with its advanced dry sorting technology, achieves precise coordination of core modules and delivers significant benefits, providing mining companies with a new path to enhance efficiency and quality in an eco-friendly manner.
Core Technology: Five Systems Build the Foundation for Intelligent Sorting
The exceptional performance of Obote’s intelligent dry sorting machine stems from its highly integrated and intelligent five core systems:
Precise Feeding System: Using variable frequency speed control and multi-layer screening technology, the system ensures that raw coal enters the identification zone in a stable, even, and thin layer. After application in a large coal mine, feedback indicated that material fluctuation dropped by over 40%, laying a solid foundation for precise identification.
High-Sensitivity Recognition System: The equipment integrates cutting-edge sensors, including high-resolution dual-energy X-rays, hyperspectral sensors, and high-speed linear array cameras. It can penetrate and analyze the density, composition, and texture differences between coal and gangue in milliseconds, with identification accuracy remaining above 95%, significantly surpassing traditional manual sorting or mechanical screening methods.
High-Speed Execution System: Based on the recognition results, ore sorting equipment uses an array of high-pressure gas valves with response speeds in the millisecond range to blow the identified gangue or impurities out of the coal flow. The injection precision can be controlled within the size of a coin, significantly reducing the loss of clean coal.
Intelligent Control System: Equipped with deeply optimized AI algorithms, the system can learn real-time changes in coal quality and dynamically adjust sorting thresholds and gas valve parameters. Zhang, a technical manager from a mine, stated, “Since the system was implemented, manual intervention has been nearly eliminated. ’15 kWh electricity savings per ton of coal and gangue content reduced to below 1%’ has become the norm.”
Closed-Loop Air Supply and Dust Removal System: This system provides stable and clean high-pressure air and is coupled with an efficient pulse dust removal device and negative pressure design. The dust concentration at the working site is consistently below national environmental standards, completely eliminating the dust-laden environment typical of traditional dry sorters and ensuring the health and safety of workers.
Industry Empowerment: Dual Leap in Efficiency and Environmental Protection
The value of Obote’s intelligent dry sorting machine has been proven in multiple scenarios:
Pre-Gangue Elimination: Efficiently removes over 80% of large gangue at the front end of the washing process, directly reducing the load and energy consumption of the subsequent water-washing system.
Thermal Coal Quality Improvement: Rapidly enhances the calorific value of commercial coal, meeting the needs of power plant customers without requiring complex water-washing processes. It is particularly suitable for arid mining areas or high-altitude regions.
Waste Reuse: The high-precision sorting system accurately separates residual coal from coal gangue, turning waste into value. It also produces high-purity gangue, providing quality raw materials for the construction materials industry.
Ideal for Small Mines and Blending Plants: The modular design makes it compact in size, with a short construction period and low operating costs, making it an economically efficient quality improvement solution for small and medium-sized coal mines or blending plants.
Through the deep integration and intelligent evolution of its five systems, Obote’s intelligent dry sorting machine has not only achieved breakthroughs in sorting accuracy and efficiency but has also set an industry benchmark in energy conservation, clean production, and reduced reliance on labor. With the country’s “dual carbon” strategy and the acceleration of intelligent transformation in mining, this advanced dry sorting technology, which is centered on advanced sensing and intelligent decision-making, will continue to drive the mining industry toward a more efficient, greener, and smarter future.
